 Description
 Schematic
The KTLP3506 series consist of a GaAs infrared
an
1
non-zero-crossing silicon bilateral TRIAC and a main
2
emitting
diode
optically
coupled
to
output power TRIAC. These devices isolate low

voltage logic from 115/240 VAC lines to provide
random phase control of high current TRIACs or
thyristors. These devices feature greatly enhanced
static dv/dt capability to ensure stable switching
